The Western States Water Council and the California Department of Water Resources cosponsored workshop in a recurring series continuing a dialogue among western states and the National Oceanic and Atmospheric Administration (NOAA), and the research community on improving sub-seasonal to seasonal (S2S) precipitation forecasting to support water management decision-making.  The agenda included topics addressing progress being made in forecasting atmospheric river storms beyond a two-week weather model time scale, assimilation of new research observations into NOAA’s weather models, scoping a pilot project for improving S2S precipitation forecasting to support Colorado River Basin drought contingency planning, and the new forecast-informed reservoir operations (FIRO) pilot project on the Santa Ana River.

The workshop was held in San Diego, California on May 14-16, 2018 at the Doubletree San Diego Downtown.  It included an optional field trip on May 17 to the Orange County Water District’s groundwater recharge facilities, which constitute part of the Santa Ana River (FIRO) pilot project.
